Amazing Ferrari Hydroplane That Chased Records In The ’50s Is Now For Sale

A beautifully styled thunderboat that was co-developed by Ferrari back in the 1950s is looking for a new home.

What you’re looking at is the 1952 Ferrari Arno XI and it is a hydroplane (or thunderboat) that was created to chase a world speed record in the 800 kg (1,763 lbs) class. It was created in collaboration with speedboat racer Achille Castoldi who pitched the project to Enzo Ferrari himself.

It is understood that Castoldi initially acquired a 4.5-liter V12 engine for the project from a Ferrari 375. Before long, Enzo determined that more power would be needed to set a new record so the engine was modified with a new compression ratio, twin spark plugs for each cylinder, and two large superchargers. All up, the engine delivered between 550 hp and 600 hp in race tune. The V12 isn’t the only unique thing about the Ferrari Arno XI.

The hydroplane has a very striking aerodynamic design dominated by hardwood that has been covered in a mahogany veneer. Meanwhile, the upper body is painted in Ferrari Red and there is a red leather seat. The hydroplane also features a massive shark fin stretching from behind the pilot’s head to the rear end.

Not only does the Ferrari Arno XI look cool but its aerodynamic shape was effective and helped it to hit a record 150.49 mph (242 km/h). The boat has since been comprehensively restored and is currently being certified at Ferrari Classiche. It last traded hands at an RM Sotheby’s auction back in 2012 where it sold for €868,000 ($1.012 million) and is now for sale from duPont Registry. The seller told Business Insider it has an asking price of $12 million.
